As everyone knows, the three swordsmen of web front-end development are HTML, CSS, and JavaScript. Through the integration of the three technologies, a variety of websites have been produced. So what do the three swordsmen of web front-end development do? What actions are mainly completed in the development of the website?
What does the Three Musketeers do for Web front-end development?
HTML is a hypertext markup language, the main content and main frame of a website page. Mainly used to implement static pages. The text, pictures, animations, sounds, forms, hyperlinks and other web page elements we see are all implemented through HTML. HTML is composed of various tags, and learning HTML is to learn how to use various tags on the basis of understanding the structure of the main HTML frame.
CSS is a cascading style sheet, which is mainly used to control and adjust the style of a web page. It has nothing to do with the structure and content of the web page. It only adjusts the different presentation styles of web content through different semantic tags. There are generally two ways to implement CSS style adjustments on webpages: inline, where CSS codes are written in the head tag of the HTML document and defined with style tags, generally located after the title tag in the head tag, in short It is a way to add CSS styles directly in the THML file; embedded is to put all the styles in one or more external style sheet files with CSS extensions, and link the external style sheet files to the HTML files through tags In short, the HTML file domain CSS file exists alone, and then the styles written by CSS are added to HTML through Link.
JavaScript is a complete web scripting language with its own independent grammar and can complete complex program logic, while HTML and CSS are only markup languages and do not have the program logic of a programming language. JavaScript is mainly responsible for various dynamic functions of web pages, so it can provide users with smoother and more beautiful page browsing effects, and add page interaction behaviors to give users a better visual and user experience. The working principle of JavaScript is that by embedding JS scripts directly in HTML web pages, functions such as corresponding browser time, reading and writing HTML element content, and changing HTML element style can be realized.
We understand the relationship between the "Three Musketeers" in an easy-to-understand way. For example, lion dance is very popular in Guangdong, my country. HTML is equivalent to the skeleton of props without decoration and people wearing ordinary clothes. CSS is to add beautiful outerwear to these props. With brilliant colors and uniform costumes for lion dancers, JavaScript stipulates the standard of lion dance movements. Only when the three are combined can people see a very attractive lion dance performance.
The above is the role of the three swordsmen in Web front-end development. In addition, in the process of learning Web front-end development, HMLT and CSS knowledge points are very easy to master, the most important thing is to learn JavaScript and JavaScript-related frameworks, such as Augular.js, Vue.js, React.js, Node.js, jQuery and many more. As the core link in website development, front-end development is the most recruited technical position in Internet companies. Especially now that the demand for multi-end development continues to increase, front-end developers have been in an undersaturated state. Therefore, as soon as possible to join the ranks of web front-end development technology learning, can win more high-quality employment opportunities for yourself.
